For most people, buying a hot water system is only a priority when building a new home, moving in, or […]
In NSW, eligible households may receive an upfront discount when replacing an existing electric or gas water heater with an eligible heat pump. The NSW Government lists indicative discounts of up to $640 for replacing an electric water heater and up to $330 for replacing a gas water heater. Actual discounts vary depending on factors such as the installer, location and system selected.
The discount is applied to the installation quote, so you do not normally receive the money as a payment after the work. The amount you actually receive can vary depending on the system, installer, and installation requirements.
What Hot Water Rebates Are Available In NSW?
There are three main forms of government support worth checking when upgrading hot water in NSW. They include the NSW Hot Water Upgrade Incentive and federal SRES, which can reduce the upfront cost of an eligible system, and Home Energy Saver, which provides repayable finance rather than a rebate.
Here is how each option works:
| Program | What You Can Get | How It Works |
| NSW Hot Water Upgrade Incentive | Up to $640 for eligible electric-to-heat-pump replacements and up to $330 for gas-to-heat-pump replacements | Upfront discount in the installer’s quote |
| Federal SRES | Typically around $800 – $1200 for some eligible heat pump systems in 2026, depending on the system, location and STC value | STC value is generally passed on through the installer |
| Home Energy Saver | Up to $15,000 as a zero-interest loan | Repayable finance, not a rebate |
You may be able to use both NSW and federal incentives for an eligible heat pump upgrade. Home Energy Saver is separate because the $15,000 support is a loan that must be repaid.
How Much Is The NSW Heat Pump Hot Water Discount?
The current NSW hot water incentive provides up to $640 when replacing an electric water heater with an eligible heat pump water heater and up to $330 when replacing a gas water heater with an eligible heat pump water heater. These amounts are indicative, so the discount shown on your quote may be different.
Electric-To-Heat-Pump Upgrade
For an eligible electric-to-heat-pump replacement, the NSW discount can be up to $640. The actual amount depends on factors such as the installer, location, heat pump model and installation requirements.
For example, if the installation price before the NSW incentive were $4,500:
Quote after Rebate: $4,500 − $640 = $3,860
Gas-To-Heat-Pump Upgrade
For an eligible gas-to-heat-pump replacement, the NSW discount can be up to $330. As with an electric replacement, the final discount depends on the particular installation rather than simply applying the maximum figure to every job.
Using the same $4,500 example:
Quote after rebates: $4,500 − $330 = $4,170
Who Is Eligible For A Hot Water Upgrade Incentive?
To qualify for the NSW hot water incentive through E-Green, you must meet four main requirements:
- Location: Your home or small business must be located in New South Wales.
- Existing System: You must be replacing an existing gas or electric water heater. If you already have an energy-efficient hot water system, you may not qualify.
- Eligible Unit: You must choose a heat pump or solar hot water system that meets the scheme’s eligibility requirements. Heat pump water heaters must have a minimum 5-year warranty against defects.
- Accredited Installer: We complete the installation and process all state paperwork on your behalf.
We apply your rebate directly as an upfront discount on your invoice, so you only pay the final reduced balance.
Does Your Existing Hot Water System Qualify?
The existing hot water system matters because the incentive is linked to the energy savings created by the upgrade. If you already have an energy-efficient system, you may not qualify, so uncertain cases should be assessed rather than treated as automatic approvals.
| Existing hot water system | Proposed upgrade | Eligibility |
| Electric storage | Eligible heat pump | Potentially eligible |
| Gas storage | Eligible heat pump | Potentially eligible |
| Gas instantaneous | Heat pump | Requires assessment |
| Existing heat pump | New heat pump | Requires assessment |
| New installation | Heat pump | Requires assessment |
The exact model and installation also need to meet the applicable scheme requirements, which is why the final answer comes from an eligibility assessment rather than the existing system type alone.
Is There A Larger Heat Pump Discount In Your Postcode?
Yes, homeowners in certain NSW postcodes can get a larger heat pump discount through the NSW Government’s Safeguard Acceleration Program. This extra support is available in selected areas and is planned to run until 30 June 2027, or until funding is exhausted.
To receive the larger amount, you must live in an eligible postcode and use an accredited business contracted under the program. When you contact us, we can check your postcode and confirm whether you qualify for the larger discount.
If your postcode does not qualify for the extra Safeguard discount, you may still be eligible for the standard NSW Energy Savings Scheme hot water discount. We check the incentives that apply to your installation and show the applicable discount in your quote.

Can You Combine NSW And Federal Hot Water Incentives?
Yes. Eligible customers may be able to use both NSW and federal incentives for the same heat pump upgrade. The NSW Government confirms that households can seek incentives from both programs when they meet the relevant requirements.
For example, if an eligible installation costs $4,500, receives the maximum $640 NSW incentive, and generates 20 federal STCs worth $800 at $40 each, the calculation would be:
| Quote Item | Amount |
| Heat pump and installation | $4,500 |
| NSW incentive | −$640 |
| Federal SRES: 20 STCs × $40 | −$800 |
| Final amount payable | $3,060 |
How Do You Claim A Hot Water Rebate Through E-Green?
To access the NSW hot water incentive through E-Green Electrical, you start by contacting our team for an eligibility assessment. We check your property, existing hot water system and installation requirements to determine which incentives may apply.
Once you qualify, we help you choose an eligible heat pump suited to your home and provide a transparent quote showing the applicable upfront discount. Before installation, we complete the required NSW nomination paperwork with you.
Our licensed team then installs the new system and completes the required documentation. You do not need to apply for a reimbursement after the installation. The applicable incentive is applied as an upfront discount to your quote, reducing the amount you pay.
The process is simple:
Eligibility assessment → heat pump selection → quote and discount → nomination paperwork → installation → reduced amount payable
What Will You Pay After The Discount?
Your final price is the amount left after the applicable incentives are taken off the system and installation costs.
Amount payable = System and installation cost − Applicable incentives
For example:
| Item | Illustrative amount |
| Heat pump and installation | $4,500 |
| NSW incentive | −$640 |
| Federal SRES incentive | −$800 |
| Final amount | $3,060 |
The final quote can change if the installation requires additional electrical work, a different installation position, extra plumbing or work involved in converting from gas.
The NSW incentive also requires a customer contribution, so the upgrade should not be presented as a completely free installation.
Which Heat Pumps Can Qualify?
A heat pump qualifies for a specific rebate or incentive only if it meets that program’s eligibility requirements. The NSW hot water incentive, federal SRES, and Home Energy Saver each have different conditions.
For the NSW hot water incentive, the replacement must meet the scheme’s product and installation requirements, and the existing system must be eligible. Heat pumps must also have a minimum 5-year warranty.
For the federal SRES, the heat pump must be an eligible model on the Clean Energy Regulator’s register, be under 425 liters, and be installed according to the registered system requirements.
For Home Energy Saver, the heat pump must meet the program’s product and eligibility rules, with the current loan available to eligible homeowners or landlords with household taxable income up to $210,000.
We check all these relevant requirements before applying an incentive to your quote. Please see our approved heat pump options to view the systems we currently offer.
Common Questions About NSW Hot Water Rebates
Is the NSW hot water upgrade free?
No. The NSW incentive requires a minimum customer payment, so the discount does not make the installation completely free.
Do I receive cash back?
No. The NSW incentive is an upfront discount included in the installer’s quote rather than a payment made to you after installation.
How Much Does It Cost To Install A Heat Pump Hot Water System In NSW?
A heat pump hot water system typically costs about $2,000 to $6,000 installed in NSW. The final price depends on the system size, model, installer, and installation requirements. Available government incentives can reduce the upfront cost.
How Much Is The NSW Heat Pump Rebate?
The NSW Hot Water Upgrade Incentive is up to $640 for an eligible electric-to-heat-pump replacement and up to $330 for an eligible gas-to-heat-pump replacement. These are indicative maximum discounts, so the actual amount included in your quote can be lower.
When Does The NSW Heat Pump Rebate End?
The standard NSW Hot Water Upgrade Incentive currently has no closing date. The NSW Government lists it as available now. The separate larger postcode-based discount is available until 30 June 2027 or until funding is exhausted.
Why Do Some Postcodes Get Larger Heat Pump Discount Amounts?
The larger discounts are targeted at selected NSW postcodes through the Safeguard Acceleration Program. The program is designed to accelerate energy-efficient upgrades in specific areas, so eligible homeowners in those areas can receive more support than under the standard discount.
How Do You Qualify For Heat Pump Discounts And Incentives In NSW?
You generally need to be in NSW and replace an eligible existing hot water system with an eligible heat pump. The system and installation must meet the relevant program requirements, and the required paperwork must be completed before installation. For the standard NSW incentive, your installer must also be partnered with an Accredited Certificate Provider.
